reversed, as in Fig. 25.5. This input, applied to C with its other
terminal virtually earthed, ensures a constant input current. Flowing
through R, this current sets up a constant output voltage, which of

course is the differential of the input; and similarly any other input
form is differentiated.
25.2 Waveform Shapers
The raw material for most non-sinusoidal waveforms—and
sometimes sinusoidal ones—is the pulse or square waveform. It can
be produced either by reshaping existing signals or by generating
them direct by special oscillators. We consider shapers first.
